About this Mod
AutoOptimizer is a lightweight client-side performance mod designed to automatically improve your FPS while you play. The mod continuously monitors your frame rate and, if it drops below the limit you set, it instantly activates smart optimization features to stabilize performance.
AutoOptimizer scans up to 13 nearby chunks around the player to detect common causes of lag such as excessive entities, particle overload, or heavy block updates. Once an issue is found, the mod applies safe, real-time adjustments to reduce strain on your client and boost FPS without interrupting gameplay.
Features:
Real-time FPS monitoring
Custom FPS threshold settings
Automatic lag detection within nearby chunks
Smart performance adjustments with no manual tweaking required
Fully client-side and server-safe
AutoOptimizer is built for players who want smoother gameplay without constantly changing video settings or installing multiple optimization mods. Just set your FPS limit once, and let the mod handle the rest
But in detail let me tell you what the mod does the mod scans the 10-30 chunks and Tries Culling enties And cull dropped items to rude client side lag while it also reduces partickles or turns them off entirely if your lagging that bad It can also cull distant players but this feature if turnerd off and can be turnerd on One last thing this mod does is reduce render distance if someone thats causing lots of lagg in another chunk it unrenders it the mod doesn't scan the 10 chunks your in but the 10 of your chunks your in right now and the most recent 3 you left After the fps is boosted the mod auto restores your settings to not messs with your personal settings
In the general tab you have 3 settings Fps threshold its auto set to 30 fps what it does is it auto activates the mod once your fps drops before 30 and tries to boost it Scan radious tells you how many chunks the mod would scan to boost your fps And Detection cooldown which is how long the mod takes before doing another scan in the background.

Does Auto Optimization need to be installed on the Minecraft server?
No. Modrinth marks Auto Optimization as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does Auto Optimization require?
Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.9, 1.21.8. Files for different loaders are not interchangeable.
Auto Optimization is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
